Orthetrum serapia, the green skimmer, is a freshwater dragonfly in the family Libellulidae. The serapia species is present in Australia, the Philippines, Fiji, Papua New Guinea and Solomon Islands. It inhabits a wide range of still and sluggish waters, often shallow. In Australia it ranges from the top end of the Northern Territory to about Mackay in central Queensland.
Orthetrum serapia is a medium-sized dragonfly with a wingspan of 60-85mm. Its wings are clear except for a small dark spot at the base of the hindwing. The thorax is greenish to greyish yellow with black markings. The abdomen is black with pale yellow or pale green markings. Orthetrum serapia appears very similar to Orthetrum sabina and can be confused where the range of the two overlaps in north-eastern Australia.
The genus name Orthetrum is derived from the Greek ὀρθός (orthos, "straight") and ἦτρον (ētron, "abdomen"), referring to the parallel-sided abdomen of the genus. The species name serapia is an eponym honouring Saint Serapia, a slave, martyr, and servant of Saint Sabina.

Rare
Under 5% of wildlife watchers report a Green Skimmer sighting in Brisbane on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 420th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and April
In those months about 10% of wildlife watchers report a Green Skimmer in Brisbane on a given day, against under 5% in March and May–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Green Skimmer sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Green Skimmer sightings, Brisbane ranks 4th at under 5%. The best odds are in Davao City (Philippines, about 30%), Cebu City (Philippines, about 30%) and Manila (Philippines, about 20%).
Same genus: Orthetrum
The closest relatives of the Green Skimmer that you can see in Brisbane (genus Orthetrum) are Fiery Skimmer (about 20%), Blue Skimmer (about 20%) and Slender Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Skimmer is recorded against all the insects logged in Brisbane (26 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
